RESUMO
Tracheobronchial amyloidosis is an uncommon localized form of amyloidosis, characterized by amyloid deposits restricted to the trachea, main bronchi and segmental bronchi. We present the case of a retired 67-year-old man with long-term progressive dyspnea, wheezing and chest pain. A diagnosis of tracheobronchial amyloidosis was made after the third fiberoptic bronchoscopy and histological confirmation through Congo red staining of tissue samples.

A amiloidose traqueobrônquica é uma forma pouco comum de amiloidose localizada, caracterizada por depósitos amilóides limitados à traquéia, brônquios principais e brônquios segmentares. Nós apresentamos o caso de um homem aposentado de 67 anos com dispnéia progressiva de longa data, sibilância e dor torácica. O diagnóstico de amiloidose traqueobrônquica foi realizado após três fibrobroncoscopias e confirmação histopatológica com coloração vermelho congo.
